Comparative Effects of Autogenic Inhibition and Reciprocal Inhibition Technique on Pain, Functional Disability and Gait in Sacroiliac Joint Dysfuction.

Sacro-iliac joint act as the shock absorber of the body. It is responsible for transferring vertical load of the whole body to lower limb hence contributing to stability of pelvic girdle. However, SI joint dysfunction is one of the most common causes of low back pain among the patients suffering from non-radicular low back pain. There can be a mechanical source which is due to muscle insufficiency or instability or a non-mechanical source which is osteoarthritis, infection or any trauma. It is thought to affect females more commonly with prevalence of about 46.71% in females and with the prevalence of about 15 to 30% in general. This poses great threat to bio mechanics of the body which can significantly lead to disability that can affect mobility, daily activities and quality of life of the individual. According to a study the pain caused by SIJD caused activity limitation and participation restriction of about 25% of the individuals. Hence making it difficult for them to continue their jobs. increased pain leads to worsening of the ability to perform ADLs which ultimately effects the quality of life. Altered biomechanics also leads to alteration in spatio temporal gait parameters.This study aims to compare the effects of autogenic inhibition technique and reciprocal inhibition technique in addition with conventional therapy in reliving low back pain, improving functional disability and alteration in spatio-temporal gait parameters in patients with sacroiliac joint dysfunction. Patients with SIJD will be recruited and will be randomly divided into two groups 20 in each group. Group 1 will receive autogenic inhibition technique of iliopsas, hamstrings, erector spinae and piriformis muscles along with standard core stabilization exercises and group 2 will receive reciprocal inhibition technique on iliopsas, hamstrings, erector spinae and piriformis muscles along with standard core stabilization exercises. The treatment will be continued for 3 weeks with 4 sessions of 25 minutes per week.
